        Nice for the price

        My wife and I had some picked out we liked more, but we are moving and needed new tires, so decided to get rims the same time so we can get both now. We are very pleased with these. I dont know enough about rims to say what is good or bad, but they make me happy with my purchase.

        Mammoth 8

        I had these wheels for just over a month now and I love the look. I have received several compliments from complete strangers regarding how nice my jeep looks with the new wheels as well. But an even better feeling is getting compliments from the people who have seen my jeep before and after the new wheels were install.

        4 2018 Rubicon - CD

        Need lugs...

        Nice looking alloy wheel. You will need after market lugs. Factory ones won't fit, at least Rubicon ones. You need cone fit lugs. Holes on Mammoths are smaller.

      If I want them to stick out further than the factory fenders, what does the offset have to be?

      • Hello! If you would like your wheel to stick further out from the car, you would want a higher negative offset.

      Any chance that this wheel will be offered in a 17x8.5 with 12mm offset to fit the Jeep Wrangler JL Sport? I want to run 285/70R17 tires and don't want the wheel sticking out too far past the fender flares.

      what is the offset please

      • The offset is -6mm (-0.2").
